About Cart Reserve: Stock Hold Timer

Overselling kills drops. You sell 500 units, refund 80, and 80 customers turn on you publicly. Cart Reserve fixes it at the source: the moment a shopper adds an item, that unit is held for them — and a tamper-proof checkout keeps it held, so it can't be bypassed by blocking scripts, forging cart tokens, or hitting the API directly. AI scores every cart-add and blocks bots before they drain stock. Expired carts auto-release inventory — no manual cleanup. Set per-product hold times, watch live act Real inventory holds — the moment a shopper adds, that unit is theirs. Tamper-proof checkout that scripts, forged tokens, and the API can't bypass. AI scores every cart-add and blocks scalper bots before they drain stock. Auto-release expired carts — no oversold orders, no manual cleanup. Live dashboard tracks active carts, save rate, and stock health in real time. Show more Show less

This app is the BEST cart reserve app I've used. It works as you WANT it to and looks really pretty too. I have tried EIGHT different cart reservation apps before this one, but they were always focused on driving sales and not ACTUALLY saving the cart so my customers have time to check out. Adam reached out to me, and i've been working closely with him since. The app is near perfect, the suppo...

I've been really impressed with the support from Adam and the team. We experienced an issue with the cart reservation feature during a very high-traffic Pokémon release. Adam responded quickly, took the time to investigate the problem with us, and was always friendly, transparent, and genuinely interested in finding a solution. Even though the app wasn't the perfect fit for our current setup, the...
